> A question: Since the data lines have to be set at a certain voltage (wit= h > resistor voltage dividers), and the battery pack voltage will vary betwee= n > 4.4 - 5.6 volts, how would I get a steady voltage on the data lines to te= ll > the iPhone to draw 1 Amp? Would I need to just stick a low power voltage > regulator at around 3.0 or 3.3 volts and create a divider from there? Consider: -Read the article/s referenced here (by me and others) that told what they did and provided circuits. - Do what they did.
